The scene with Cassian’s introduction with the spy, Bodhi traipsing through Jedha on his way to see Saw, these are things that were added.
We wanted to make more of the other characters, like Cassian’s character [Cassian Andor, the Rebel spy played by Diego Luna], and Bodhi’s character [Bodhi Rook, the defected Imperial pilot played by Riz Ahmed].
The story was reconceptualised to some degree, there were scenes that were added at the beginning and fleshed out.
